Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a mop head deceleration disc. Background Technology

[0002] Spin mops are increasingly popular due to their convenient washing and wringing capabilities, especially their ability to achieve a semi-dry cleaning effect. Their basic principle involves the mop base rotating along with the spin-dry basket or washing disc inside the tub, thus achieving centrifugal dehydration or mop washing. Most spin mops use a hand-operated drive mechanism to rotate the mop base. During spin-drying, the mop base drives the spin-dry basket to rotate, achieving centrifugal dehydration; during washing, the rotation of the mop base similarly drives the washing disc to rotate, agitating and washing the mop in the water.

[0003] However, during washing, due to water resistance, the user needs to apply greater downward pressure to drive the mop handle and rotate the washing tray, making it difficult to achieve the washing function. Furthermore, once it starts rotating, excessively high speeds can cause water to splash out of the tub. Therefore, most hand-operated spin mops currently on the market only have a spin-drying function, resulting in inconvenience during use.

[0004] To overcome the aforementioned shortcomings, some dual-speed rotary mops have emerged. For example, invention patents CN104720705A and CN102319048A achieve dual-speed operation during spin-drying and washing. However, these patented solutions all require a locking mechanism and a retainer between the mop head and the washing head mounting base to limit the deceleration mechanism's operation, resulting in a relatively complex structure and a higher failure rate.

[0005] Therefore, it is necessary to develop a mop head deceleration disc to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a mop head deceleration disc with a compact and ingenious structure, which also simplifies the structure of the mop bucket and has a low failure rate.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model relates to a mop head deceleration disc, comprising a mop handle assembly, a sun gear, a planetary disc, a disc retainer, planetary gears, and an outer disc. The mop handle assembly is pinned to a plug at the top of the sun gear. The planetary disc is coaxially and rotatably mounted below the sun gear via the disc retainer. The outer disc is coaxially and rotatably sleeved on the outside of the sun gear. The planetary gears are driven between the teeth of the sun gear and the external gears on the inner side of the outer disc. Multiple planetary gears are rotatably connected to a planetary gear axle at the top of the planetary disc. A slot is provided at the center of the bottom of the planetary disc for connecting the square plug of the mop bucket's cleaning seat and the square plug of the spin-dry basket. The bottom of the outer disc is connected to the mop cloth via a snap-fit ​​mechanism.

[0009] Furthermore, the wheel clamp is a cylindrical structure with claws. The inner folded edge at the top of the wheel clamp is engaged with the outer folded edge at the bottom of the sun wheel. The bottom of the wheel clamp is provided with four claws, which are engaged in the clamping holes of the planetary wheel.

[0010] Furthermore, the mop handle assembly includes a handle fork head body and a tightening sleeve. The top of the handle fork head body is provided with an insertion hole with a side wall groove. The tightening sleeve is threaded onto the external thread on the outer wall of the insertion hole. The insertion hole is fitted onto the bottom end of the mop handle and locked by the tightening sleeve.

[0011] Furthermore, the mop handle assembly also includes a positioning clip and a sleeve. The sleeve is fitted onto the plug at the top of the sun gear component. The sleeve has an oblong hole. The fork of the handle head body is connected to the oblong hole and the pin hole of the sun gear component plug by a pin. The positioning clip is installed at both ends of the pin by countersunk screws. The positioning clip can be rotated circumferentially by the fork of the handle head body. The bottom of the positioning clip is provided with a pressure block protrusion that presses against the base of the sleeve.

[0012] Furthermore, a lower positioning post is coaxially provided at the bottom end of the sun gear component, and a positioning hole is centrally provided at the top end of the planetary disk, the positioning hole being rotatably fitted onto the lower positioning post.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model of a mop head deceleration disc achieves two speeds: decelerated output to the outer disc and synchronous direct output, by directly setting a slot in the middle of the bottom of the planetary wheel, and then connecting the slot to the square plug of the washing seat or the square plug of the spin-drying basket. This utility model of a mop head deceleration disc does not have a ratchet for connection, nor does it have a locking platform or locking seat. Compared with the deceleration mechanism in the prior art, it has a compact and ingenious structure, simplifies the structure of the mop bucket, and has a low failure rate.

[0015] Furthermore, the claws of the wheel disc retainer engage with the retaining holes of the planetary wheel disc, enabling rapid coaxial assembly of the planetary wheel disc and the wheel disc retainer. The blocking protrusions and blocking side plates prevent the planetary wheel disc from detaching from the wheel disc retainer. The insert hole allows for secure connection to the mop handle by fitting it onto the bottom of the mop handle and tightening it with a screw-on sleeve. By adding a sleeve head and a positioning clip, when the mop handle head assembly and mop handle are coaxial, the pressure protrusion of the positioning clip pushes downwards to press against the sleeve head base, and the oblong hole presses the pin into the pin hole, achieving effective connection between the mop handle head assembly and the sun gear assembly. The coaxial connection between the planetary wheel disc and the sun gear assembly is ensured by the cooperation of the planetary wheel disc's positioning hole and the lower positioning pin.

Detailed Implementation

[0023] The core of this utility model is to provide a mop head deceleration disc, which has a compact and exquisite structure, simplifies the structure of the mop bucket, and has a low failure rate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the mop head deceleration disc of this utility model; Figure 2 This is a three-dimensional structural diagram of the mop head deceleration disc of this utility model from another angle; Figure 3 This is a schematic diagram of the main structure of the mop head deceleration disc of this utility model; Figure 4 for Figure 3 Schematic diagram of the cross-sectional structure along the middle AA direction; Figure 5 This is a three-dimensional structural diagram of the present invention after the outer wheel is removed.

[0027] In one specific implementation, such as Figures 1-5 As shown, the mop head reduction disc of this utility model includes a mop handle assembly 1, a sun gear 2, a planetary disc 3, a disc retainer 4, planetary gears 5, and an outer disc 6. The top of the mop handle assembly 1 is connected to the mop handle, and the bottom pin of the mop handle assembly 1 is connected to the plug at the top of the sun gear 2. The planetary disc 3 is coaxially and rotatably mounted below the sun gear 2 via the disc retainer 4. The outer disc 6 is coaxially and rotatably sleeved on the outside of the sun gear 2, and the planetary gears 5 are driven between the teeth of the sun gear 2 and the external gear 601 on the inner side of the outer disc 6. Multiple planetary gears 5 are rotatably connected to the planetary gear axle bracket 301 at the top of the planetary disc 3; in one specific embodiment, the number of planetary gears 5 is three. A slot 302 for connecting the cleaning seat plug and the spin-dry basket plug of the mop bucket is provided at the middle of the bottom of the planetary disc 3. The bottom of the outer disc 6 is connected to a retainer via a snap-fit ​​mechanism, which holds the mop cloth between the outer disc 6 and the retainer.

[0028] The working principle of this utility model's mop head reduction disc is as follows: When the slot 302 is inserted into the cleaning seat plug of the mop bucket, because the cleaning seat plug is fixed, the planetary gear 3 cannot rotate. The mop handle drives the mop head assembly 1 to rotate, which in turn drives the sun gear 2 to rotate. The sun gear 2 drives the planetary gear 5 to rotate on its own axis, but the planetary gear 5 does not revolve around the sun. At this time, the planetary gear 5 is driven to rotate by the planetary gear 601. However, the number of teeth on the external gear 601 is greater than the number of teeth on the sun gear 2, and the ratio of their tooth counts is the reduction ratio at this time. Ultimately, this achieves the goal of driving the mop cloth to rotate at a low speed inside the cleaning bucket, thus achieving a labor-saving washing effect. When the slot 302 is inserted into the square plug of the spin-dry basket of the mop bucket, the square plug of the spin-dry basket and the stainless steel spin-dry basket are integrated and can rotate relative to the mop bucket. At the same time, the mop cloth is clamped between the side wall of the stainless steel basket and the outer wheel 6, so the outer wheel 6 cannot rotate relative to the planetary wheel 3. When the two cannot rotate relative to each other, the planetary wheel 5 that reduces speed is locked. At this time, the mop handle assembly 1 drives the stainless steel basket to rotate synchronously at high speed for centrifugal spin-drying.

[0029] By directly setting a slot 302 at the bottom center of the planetary wheel 3, and connecting the slot 302 to the washing seat plug or the spin-drying basket plug, two speeds are achieved: deceleration output to the outer wheel 6 and synchronous direct output. The mop head deceleration disc of this utility model does not have a ratchet for connection, nor does it have a locking platform or locking seat. Compared with the deceleration mechanism in the prior art, the structure is compact and exquisite, and it also simplifies the structure of the mop bucket, resulting in a low failure rate.

[0030] In one specific embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the wheel clamp 4 is a cylindrical structure with clamping claws. The inner folded edge at the top of the wheel clamp 4 is engaged with the outer folded edge at the bottom of the sun gear 2 to prevent it from axially dislodging downwards. The bottom of the wheel clamp 4 is provided with four clamping claws, which are evenly distributed and spaced apart around the circumference. The clamping claws are engaged in the clamping holes of the planetary wheel 3.

[0031] Specifically, such as Figure 4 As shown, the planetary gear 3 has a blocking protrusion at the position of the pawl, and blocking side plates on both sides to prevent circumferential rotation. The outer ring of the planetary gear 3 has an upward-facing flange that closes the bottom edge of the external gear 601.

[0032] The planetary wheel 3 and the wheel clamp 4 are quickly and coaxially assembled by the claws of the wheel clamp 4 engaging with the clamping holes of the planetary wheel 3. The blocking protrusions and blocking side plates prevent the planetary wheel 3 from detaching from the wheel clamp 4.

[0033] In one specific embodiment of this utility model, such as Figures 1-4As shown, the mop handle assembly 1 includes a handle fork head body and a tightening sleeve 101. The top of the handle fork head body is provided with an insertion hole with a slotted side wall. The tightening sleeve 101 is threaded onto the external thread on the outer wall of the insertion hole. The insertion hole is fitted onto the bottom end of the mop handle and locked by the tightening sleeve 101.

[0034] Specifically, such as Figures 1-5 As shown, the mop handle assembly 1 also includes a positioning clip 102 and a sleeve 103. The sleeve 103 has a thin-shell structure, and its upper part is fitted onto the plug at the top of the sun gear 2. The upper part of the sleeve 103 has a vertically oriented oblong hole. The fork of the handle head body is connected to the oblong hole and the pin hole of the sun gear 2 plug by a pin. The positioning clip 102 is installed at both ends of the pin by countersunk screws, and the positioning clip 102 can be rotated circumferentially by being turned by the fork of the handle head body. The side wall of the fork of the handle head body has a receiving groove, and the side wall of the positioning clip 102 facing the fork has a protrusion that engages with the receiving groove. The bottom of the positioning clip 102 has a pressing block protrusion that presses against the base of the sleeve 103.

[0035] The mop head assembly 1 is connected to the bottom of the mop handle by means of the insertion hole and locked by the tightening sleeve 101. By adding the sleeve head 103 and the positioning clip 102, when the mop head assembly 1 and the mop handle are coaxial, the pressure block protrusion of the positioning clip 102 pushes down to press the base of the sleeve head 103, and the waist-shaped hole presses the pin in the pin hole, thus realizing the effective connection between the mop head assembly 1 and the sun wheel 2.

[0036] In one specific embodiment of this utility model, a lower positioning post 201 is coaxially provided at the bottom end of the sun gear component 2, and a positioning hole is provided in the center at the top of the planetary disk 3. The positioning hole is rotatably and coaxially sleeved on the lower positioning post 201.

[0037] The coaxial connection between the planetary disk 3 and the sun gear 2 is ensured by the cooperation of the positioning hole of the planetary disk 3 and the lower positioning post 201.

[0038] In summary, this utility model of a mop head deceleration disc achieves two speeds: decelerated output to the outer disc 6 and synchronous direct output, by directly setting a slot 302 at the center of the bottom of the planetary disc 3. The slot 302 then connects to the square plug of the washing seat or the square plug of the spin-drying basket. This utility model of a mop head deceleration disc does not use a ratchet for connection, nor does it have a locking platform or seat. Compared to existing deceleration mechanisms, it has a compact and sophisticated structure, simplifies the structure of the mop bucket, and has a low failure rate. Furthermore, the claws of the disc retainer 4 engage with the locking holes of the planetary disc 3, enabling coaxial and rapid assembly of the planetary disc 3 and the disc retainer 4. The blocking protrusions and blocking side plates prevent the planetary disc 3 from detaching from the disc retainer 4. The mop head assembly 1 is connected to the bottom of the mop handle via the insertion hole and locked by the tightening sleeve 101, effectively connecting it to the mop handle. With the addition of a sleeve head 103 and a positioning clip 102, in a coaxial state between the mop head assembly 1 and the mop handle, the pressure protrusion of the positioning clip 102 pushes downwards to press against the base of the sleeve head 103. The oblong hole presses the pin into the pin hole, achieving an effective connection between the mop head assembly 1 and the sun gear 2. The coaxial connection between the planetary disc 3 and the sun gear 2 is ensured by the cooperation of the positioning hole of the planetary disc 3 and the lower positioning pin 201.
